Ingredients:
- 500g (4 cups) all-purpose flour
- 300g (2 1/2 cups) whole wheat flour
- 700g (2 3/4 cups) water, at room temperature
- 150g (3/4 cup) active sourdough starter
- 10g (2 tsp) sea salt
Instructions:
- In a large bowl, combine the all-purpose flour, whole wheat flour, and water. Mix until no dry flour remains. Autolyse for 1 hour.
- Add the active sourdough starter and sea salt to the dough. Mix until fully incorporated, using the pinch-and-fold method.
- Cover the bowl with a damp cloth and let it rise for 4-6 hours at room temperature. During the first 2 hours, perform stretch-and-fold every 30 minutes.
- Gently turn the dough onto a lightly floured surface. Pre-shape into a round and let rest for 30 minutes.
- Shape the dough into a round or oval loaf, tucking in the edges. Place seam side up in the banneton.
- Cover with a cloth and let it proof for 1-2 hours, or refrigerate overnight for better flavor.
- Preheat your oven to 450°F (230°C) with a Dutch oven inside.
- Carefully transfer the dough to the preheated Dutch oven. Score the top with a sharp blade, cover, and bake for 30 minutes.
- Remove the lid and bake for an additional 15-20 minutes until golden and hollow sounding.
- Let the bread cool on a wire rack for at least 1 hour before slicing.
